My dad was driving on the M62 once, a pickup truck in front had a loose wheelbarrow on the back, it flew off and caused about £500 worth of damage to his laguna. Needed new front bumper, new headlight assembly, new wing, new bonnet. Thankfully covered by my dad's insurance, but not the pickup's, since my dad didn't get his reg. Bet the guy got a shock when he arrived and found he was lacking a wheelbarrow. Wonder if he went back and found it on the central reservation of the M62 c/w a scratch-coat of metallic blue paint and one almighty dent???
